The Yomiuri ShimbunThe world’s smallest and lightest artificial heart-lung apparatus has been developed by the National Cerebral and Cardiovascular Center in Suita, Osaka Prefecture, the center announced. The device is small enough to be used in medical emergencies outdoors or on air ambulances.

The center plans to begin clinical tests in fiscal 2019, aiming to put the portable equipment into practical use as soon as possible.

Extracorporeal membrane oxygenation (ECMO) devices use a pump to circulate blood in patients with heart and lung disorders. The devices are used in over 8,000 cases annually. Because of the large size of existing devices, it is difficult for them to be used outside of intensive care units.

The newly developed apparatus is 29 centimeters wide, 26 centimeters high and 20 centimeters deep.

Weighing only 6.6 kilograms, the portable apparatus, which also functions as a heart and lung monitor, is less than half the size of conventional devices.

Equipped with batteries and removable oxygen tanks, the apparatus can be used for over an hour in sites without power or oxygen supplies.Speech
